NASA Study Finds Warmer Future Could Bring Droughts

The researchers compared historical records of the climate impact of changes in the sun's output with model projections of how a warmer climate driven by greenhouse gases would change rainfall patterns. They found that a warmer future climate likely will produce droughts in the same areas as those observed in ancient times, but potentially with greater severity.

Secondo la NASA un aumento della radiazione solare unito all'effetto serra potrebbe dare origine a conseguenze assai disastrose modificando la piovosità e creando siccità in diverse aree geografiche.

There is some evidence that rainfall patterns already may be changing," Shindell added. "Much of the Mediterranean area, North Africa and the Middle East rapidly are becoming drier. If the trend continues as expected, the consequences may be severe in only a couple of decades. These changes could pose significant water resource challenges to large segments of the population.

In particolare prevedono un aumento della siccità, specie nell'area del Mediterraneo, già nel giro di due decadi.
